Welinq: Europe's Quantum Memory Pioneer Enabling Secure Quantum Networks

Welinq is a Paris-based deep-tech venture driving a new era of quantum connectivity. Founded in 2022 as a Sorbonne University spin-off, the company has rapidly translated world-leading laboratory research into deployable quantum hardware. Its flagship innovation – a neutral-atom quantum memory with record-setting efficiency – addresses a critical bottleneck in scaling quantum computing and secure communication networks. By enabling multiple quantum processors to be entangled and networked, Welinq’s technology lays the groundwork for distributed quantum data centres and quantum-secure communications.

In a strategic context, this capability is pivotal for Europe: it strengthens technological sovereignty by replacing reliance on foreign quantum components, enhances NATO’s secure information infrastructure, and contributes to the EU’s ambition to lead in emerging technologies. As geopolitical competition in quantum tech intensifies, Welinq emerges as a key European asset bridging cutting-edge science and defence-oriented applications. Welinq is a deep-tech startup (academic spin-off) that develops quantum networking hardware and software centered on the world’s most efficient quantum memory. This French company aligns with European emerging and disruptive technology priorities in quantum computing and secure communications.

Its innovations directly support European strategic autonomy by substituting extra-EU suppliers in a field dominated by US and Chinese initiatives. Welinq’s quantum memory and interconnect solutions bolster NATO interoperability through future quantum-safe communication links and multi-domain quantum computing clusters. The company plays an active role in EU programs (EIC, Quantum Flagship) and collaborates with European quantum primes, indicating strong European defence technological and industrial base (EDTIB) integration. By enabling secure, high-performance quantum networks, Welinq enhances collective deterrence (through unhackable communications and faster data processing) while maintaining transatlantic compatibility under European sovereign control.
